PACKAGE-SEALING DEVICE.

SPECIFICATION forming part of Letters Patent NO. 628,771, dated Tilly l1, 1899.

Application led February 18, 1899. Serial No. 705,988. (No model.)

Be it known that I, JOSEPH T. GRAW, of Jersey City, in the county of Hudson and State of New Jersey, have invented a new and useful Device for Sealing Packages, of which the following is a full, clear, and exact description. l

The object of my invention is to provide a simple economic device whereby the end iiaps drawings, forming a part of this specification,

in which similar1 characters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective View of the complete device. Fig. 2 is a plan view of the main table of the device or that portion that is adapted to close and seal yan end of an empty box. Fig. is a section taken substantially on the line 3 3 of Fig. 2. Fig. is a section taken also on the line 3 3 of Fig. 2, illustrating one flap or wing of the box in position to be closed. Fig. 5 is a section similar to Fig. 4, illustrating the iiap shown in Fig. f1 as in position to be sealed, as having been sealed, and the opposing iiap in position to be closed and sealed. Fig. (i shows in dotted lines a box with a tiap in position to be closed over a flap Valready closed, said box having been moved to a different position on the table than the position the box occupies in Fig. 5, Vand said figure also shows in positive lines a vertical section on the line 6 6 in Fig. 9 of a box, the bottom flaps of which have been sealed. Fig..7 is aperspective view ot' a box viewed from the` bottom, illustrating the manner in which the sealing compound is applied to the bottom of said box. Fig. 8 is a perspective view `of a box, the bottom of which has been completely closed. Fig. 9 is a partial pla-n viewof the improved table adapted for closing the bottom of the box, illustrating in dotted lines the various positions the box occupies while its bottom is be ing closed. Fig. 10 is a plan view of a series of boxes, showing the manner in which their upper ends are sealed, sundry of the boxes being shown completely sealed uand others partially so 5 and Fig. 11 is a transverse section taken practically on the line 1l 1l of `A represents a table or a board that is sup ported in any suitable or approvecbmanner, but which may rest directly upon an independent support cf any character. The table A is provided with a rib or iiange 10 at its left-hand side, extending fromthe front to a point near the rear, and between the ends of the flange 10 a transverse opening 11 is made in the table, asv shown in Fig. 1l, the opening being adjacent to the said tiange 10. This opening is partially closed by plates 12, that fit in rabbets 'formed in the walls of the openin g, and the said plates are so arranged as to provide two longitudinal slots 13, and a disk 14 is made to extend through the opening 13, that is nearest the flange 10, while a second disk 14: extends :into the opening 13 farthest removed from said iiange. These disks may have a brush-periphery, or their peripheral surfaces may be prepared in any manner that will enable said surfaces to carry paste, glue, or other cementing material to the uppersuri'ace of the table.

The disk 1i is secured upon ay shaft 15, while the diskli is adjustably attached to said shaft, and, as shown in Fig. ll, the shaft 15 is mounted in a trough 1:1', said trough being adapted to contain paste, glue, or other cementing compound. In order that the disk cement-distributers may not become clogged,

members may extend out at each side'of the disk cement-distributers.

A transverse opening 1i) is made 'in `the ta-` ble A, the said opening extending usually from ,the right-hand side to the dange 10 at the left-hand side of the table. This openreo Y to the upper portion of the table.

ing 19 is between the rear edge of the table and the opening 11, at which the devices are attached for conducting celneuting material The opening 19 is in two Widths, the wider section 19tL being adjacent to the left-hand side of the table and the narrower section 19b of the opening extending toward the righthand side, as is clearly shown in Figs. 2 and 9. The rear wall of the opening 19 is practically straight throughout its length and the forward wall of the narrower section 19b of the opening may be either beveled or straight, while the rear wall a of the wider section 19n of the opening is curved upwardly and rearwardly or is inclined in such direction as may be desired.

A plate20, provided with apertures 21, is secured in any suitable or approved manner tothe upper portion of the rear end of the flange 10. An adjustable guide-bar 22 is made to extend transversely of the upper face of the table and beneath the plate 2 the guide-bar 22 being provided with a series of apertures 23, and thesaid guide-bar is adjusted transversely or longitudinally of the table by passing a pin 24 through one of the openings 21 in the plate 2O and a`suitable opening 23 in the guide-bar.

A longitudinal guide-bar 25 is located upon the upper face of the table at or near the right-hand end of the transverse guide-bar 22, and the forward end of the longitudinal guide-bar 25 is held in desired position by passing a pin 26 through an aperture in the longitudinal guide-bar and one of a series of transversely-arranged apertures 27 made in the table adjacent to the forward edge of the narrower portion of the opening 19 in the table. The longitudinal guide-bar 25 is at a right angle to the transverse guide-bar 22. and said longitudinal guide-bar 25 is provided at its rear end with a plate 29, secured to the upper surface of said guide-har 25, Said plate having apertures 29 made therein, so that the transverse and the longitudinal guide-bars may be adjustably connected by passing a pin 28 through any one of the apertures A29a in the longitudinal guide-bar into any one of the apertures 23 in the transverse guide-hagas is particularly shown in Fig. 9. A second transverse guide-bar 30 is located upon theupper face of the table between the opening 19 and the forward edge of the table, and said second transverse guidebar 30 extends from the right-hand side of the table usually overthe right-hand coverplate 12 for the opening 1 1 in the table. .This second transverse guide-bar is adjustable, being attached to the table through the medium of two pins 34 and 34a, located one at each side of its center, and said bar 30 is rendered adjustable by attaching a link 31 to its central portion, the other end ofthe link being pivotally attached to said table. Series of apertures 32 and 33 are eccentrically 1ocated in the table, and as the guide-bar 30 is moved it may be held in adjusted position by passing the pins 34 and 34"L through any one of the series of apertures 32 and 33, as is illustrated in dotted lilies in Fig. 9.

In connection with the table A an auxiliary table B is preferably employed, the upper faces of the two tables being in the same horizontal plane. Usually at the right-hand end of the auxiliary table B a trough C is supported hy suitable legs 34b or their equivalents. The said trough is provided with a set of rollers D at or near each of its ends, one roller 35 of each set being adapted to turn in the trough, while the other rollers 36 of the sets revolve out of the trough and above the lower rollers quite near thereto, the upper rollers being journaled in suitable bearings 37. The upper roller 36 of the outer set of rollers is provided with a longitudinal blade 38,extending, preferably, from end to end,and a combined tension and guide roller 39 is journaled Within said trough C between the two sets of rollers D. A strip of paper 40 is fed between the outer set of rollers under the combined guide and tension roller 39 and between the rollers of the inner set D, as illustrated in Fig. 1, and as the upper roller of the outer set D is revolved by drawing the paper between the rollers, the blade 38,which is provided with series of teeth or pins, produces transverse perforar-ions 41 in the paper at regular intervals, and the space between adjacent perforations corresponds to the space between the edges of the box to be sealed, at which thev innermost llaps or wings are located.

Each box E is provided with corresponding flaps or wings at top and bottom, comprising what may be termed opposing inner flaps or wings 42 and 43 and outer or sealing flaps or wings 44 and 45, the outer sealing aps or wings 44 and 45 being adapted to fold upon each other and upon the inner flaps or wings 42 and 43 when the latter have been folded inward.

A tray 46 is provided to receive the filled boxes E, the tray being open at one end, and after, an end of an empty box has been closed and sealed by its travel overt-he main table A said empty box is brought beneath a hopper 47, suitably supported and adapted to contain the material with which the box is to be lilled, or for the hopper 47 maybe substituted any equivalent device that may be convenient or advisable. v

In the operation of the device, when an empty box is to be closed at its bottom end, the inner wings or tlaps 42 and 43 are carried horizontallyinward in direction of each other, as shown in Fig. 7, and the outer or sealing flaps or Wings 44 and 45 are carried horizontallyoutward. The wings or flaps being in the position just described, the bottom of the box is placed upon the table A near the front and against the inner face of the flange 10 in such manner that the outer flap or Wing 45, for example, Will face to the rear and the 0p- IOO IIC

i reference numeral 46a.

posing corresponding flap or wing 44 will face to the front, as shown in Fig. 9. The box is then carried rearward, guided by contact with the flange 10, and as the bottom of the box passes over the disks 14 and 14 the cement or paste on the peripheries of these disks will be deposited on the inner faces of the outer or sealing fiaps or wings 44 and 45 and upon the outer faces of the inner flaps or wings 42 and 43, as shown in Fig. 7, in which figure the deposited cement is designated by the After the box has passed the cement-applying devices the rear flap or wing 45 will drop down into the larger portion 19 of the opening 19, and as the box is carried fartherrearward to an engagement with the rear transverse guide-bar 22 the flap or Wing 45 will engage with the bevelededge Yd of the larger section of the opening 19 and will be carried toward and made to adhere to the inner closed flaps or wings 42 and 43, especially when the Wing or flap 45 is brought in its folded state upon the upper face of the table, as shown indotted lines in Fig. 9 and in positive lines in Fig. 5, the fiap 45 before being carried to a contact with the folded flaps 42 and 43 being illustrated in Fig. 4. When the box has been carried rearward to an engagement with the transverse cross-bar 22 and the flap or wing 45 has been sealed and closed, the opposing liap 44 will extend down K into the Wider portion'19 ofthe opening 19,

as shown in dotted lines in Fig. 6 and in positive lines in Fig. 5. The box is now slid toward the right along the surface of the table at the rear ofthe slot 19 until the longitudinal guide-bar 25 is reached, as shown in dotted lines alsoin Fig. 9. When the box reaches this position, said box is carried forward in engagement with the longitudinal guide-bar 25, and the fiap 44, engaging with the forward edge of the slot 19, will be folded up in like manner as the flap 45 andwill adhere to the fiap 45 and the portions of the inner flaps 42 and 43 not covered by the outer or sealing flap 45. In this manner the bottom of the box is perfectly closed, and said closing is rendered smooth by continuing the box for- Ward until it strikes the forward transverse guide 30, the box being then carried to the right-hand side of the table in contact with this latter guide and beneath the hopper 47 or other supply,whereit may be filled. After a' series of five boxes, for example, has been filled these filled boxes are placed in the tray 4G, which is at the deliveryen'd ofthe trough C. The trough @contains a paste or cementing compound of any description, and as the perforated strip of paper passes beneath the combined guide and tension roller `39 this strip of paper is coated on bot-h sides with said cementing material. The filled boxes being in position close to one another and the inner liaps 42 and 43 having been folded down upon the contents, as shown in Fig. 1, a sufficient length of the cement-coated paper 40 is Y drawn from between the series of rollersD to provide a stri-pcf paper that 'will extend from one end package to the other across the folded inner flaps 42 and 43, the perforated portions 41 of the strips of coated paper registering with the space between adjoining pack' ages or boxes. The outer or sealing fiaps or Wings 44 and 45 at thetop portion of the packages or boxes are now carried over upon the coated paper, and in this manner thecoated paper serves as a binder or cementing agent between the inner and the outer iiaps or Wings, closing the top end of the package or box practically in an air-tight manner.

4It is evident that when the boxes or packages are separated the coated paper will part at the lines of perforations. For the plates 12 other plates, larger or smaller, may be s ubstituted, so that the disks 14 14 may be adjusted to produce a proper gumming of the surfaces of flaps or Wings of boxes of different sizes.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A device for sealing boxes, consisting of a surface over which the portion of the box to be closed is passed, said surface having an opening adapted to alternately receive the sealing-flaps of a box, the Walls of the opening being arranged to direct the fia-ps to a closed position, means for su pplyin ga cementing material to the said surface, and guides defining the path in which the box is to be moved, as described.
